In my 1000
BCC FOC micro set I have 100 paulson nickels & 60 of my (210) dimes are Paulson; I notice no difference between the two brands with regard to sound or feel. Previously I had a mix of quarters in the set and noticed no difference, with regard to sound and feel, between them either.
I haven't seen any QC issues regarding the inlays & the differing order of the cards between the two brands probably wouldn't be noticed by a non-chipper.
The only mix I have left is the dimes; a barrel of each weighs in at 180g
A barrel of the Paulson nickels weighs in at 174g
A barrel of the
BCC quarters weighs in at 162g
A barrel of the
BCC 50¢ chips weighs in at 166g
A barrel of the
BCC dollars weighs in at 170g
A barrel of the
BCC $5 chips weighs in at 164g, and
A barrel of the
BCC $25 chips weighs in at 173g
There is an obvious difference in the shade of color between each brand's matching denoms. I don't mind the difference too much between my dimes, nor did I mind the difference in the quarters before moving the Paulsons out of the set (I just had too many quarters so the Paulsons had to go). I know of another member who has a mix of nickels and he does not care for the color difference between them.
I don't think the differences between the brands prohibit them from working well together but, as the saying goes, YMMV.
I like that my set is not sitting on a shelf waiting to be 'purified' into a s single-brand set (I have enough of those!), it's a playable work in progress.
It's also nice that the FOC chips of either brand are available and relatively inexpensive (away from
eBay).
I personally don't think either brand is better than the other (in this chip line) but mixing the two, especially within the same denoms, may lead to some level of dissatisfaction for some.
